.mssE e. VINCENT, or DETROIT, MICHIGAN, as'sIoNoR 'ro PACKARD MoroR CAR COMPANY, or DETROIT, MICHIGAN, A CORPORATION or MICHIGAN.-

IIYDRocARRoN-MOTOR.

of Detroit, lilfayne county, vState oli' Michigan, have invented certain new and useful improvements in Hydrocarbon-Motors, ot ywhich the following is a specification.

This invent-ionrelates to hydrocarbon motors and particularly to V-type motors .in which the valve operating mechanism is ar ranged between the cylinder castings,

@ne of the objects ot thev rinvention is to provide a support for the Avalve operating mechanism separate from the cylinders.

Another object is to provide parallel supports for two sets of rock arms for operating the various'valves oi the cylinders.

Another object is to provide springs for ,seating the valves and additional springs tending to move the push rods away from the valves.

@ther objects of the invention will appear from the following description taken in connection with/the drawings which 'form a part of this specification, and in which:

Figure 'l is a view partly in section of a .hydrocarbon motor embodying one form of the invention; f

Fig. 2 is a sectional plan View; and

llig. 3 is a detail view ot' another. form of valve operating mechanism.

In the drawings, l() designates the crank case of a hydrocarbon motor on which are mounted two bloclrs ol cylinders 1l and I2 in V relation. A crankshaft 13 is mounted in the crank caseand is connected to the cylinder pistons 14 by connecting rods l5.

'Eachycylinder is provided .witlna combustion space 16 and vertically. extending valve pockets 1'7. On the' inner side of cachot' the pockets are provided inlet and exhaust ports 18 and on the outer side, opposite these ports, are openings 19 normally closed by plugs20. Spark plugs 21 are mounted in the cylin-v ders in communication with the combustion space. f f

Valves 22, preferably of the puppet type, control the ports land 'are yieldingly held i to their seats by springs 23 surrounding` the valve stems 24 which are mounted in guides' l 25 and extend inwardly from thel cylindersl in a. horizontal plane.

Mounted on the crank case 10 between and independently of the cylinders is a casing 26y for inclosing the valve operating Specicationof Letters Patent.

mechanism. A cam shaft 27 suitably driven from the crank shaft 13 is' rotatably mounted in thecasing 26. Above and on leither side of the cam shaft are parallel shafts 2S, on which rock ,arms 29, arranged inv staggered relation, oscillate. The lower end` of each rock arm carries a roller 30 which bears against an actuating cam 31 on the shaft 27 while the -upper end is split to adjustably clamp a pin 32 by which the'loscillation is transmitted to the valve stem through push rods lThe push rods 33 are mounted in the casing` 26, each rod being alined with a valve stem to transmit the impulse .from the i rocker arm to its respective valve stem. Each push rod Is guided by a. sleeve 34 and yicldmgly held against the rocker arm by springs The valve stems are yieldingly held in contact with the push rods by the springs 23 so that the valve stems follow the return movement of the push rods'.

Fig. 3 shows-another form of valve oper ating mechanism. In this form the push rod 42 which operates against the valve stem 24, is securedr in an ear ll on a ring 36 surrounding tho cam A roller t3 follows however, other forms can-be created which will fall Within the scope ot this invention and it is intended to cover all such constructions in the following claims.

v Having thus described my invention, what l. In a hydrocarbon motor, in combination, cylinders arranged in V-iform, aicasing arranged between said. cylinders and supportedl independently thereofJ horizontally arranged valves in the cylinders, andvalve operating mechanism in said casing. p

2.111 a hydrocarbon motor, in combination,"cy linders arranged in V-fcrm, a casing `arranged between said cylinders and sup` ported independently thereof, horizontally vsaid casing' and having tion, cylinders arranged in V-form, a casing "arranged between said cylinders, a cam shaft in said casing, parallel shafts arranged side by side in said casing, rocker arms on one of said parallel shafts adapted to operate valves in the cylinders farthest therefrom, and rocker arms on the other parallel shafts adapted to operate valves in the other cylinders.

4. In a hydrocarbon mo'tor, in combination, cylinders arranged .in V-form, horizontally arranged valves in 'said cylinders, horiz'ontally arranged push-rods for said valves, rocker arms for said push rods arranged in staggered relation, and la single cam shaft `to operate said rocker arms.

5,. In' a hydrocarbon motor, in combination, cylinders arranged in V-form, horizon,- tall-y arranged valves in said cylinders,'hori zo'ntally arranged push-rods for said valves, rocker arms' for 'sald push-rods arranged in staggered relation, parallel Vsupports for said arms, and a single cam shaft arranged beneath said ,supports and adapted to operate all of said arms.

6. In a hydrocarbon motor, in combination, motor cylinders, valves therein, a cam.

shaft, a pair of shafts mounted above and parallel to said cam shaft, rocker arms on said parallel shafts in operative relation with the cam sha-ft, and push-rods extendin from said arms to the valves.

g. In a hydrocarbon motor, in combination, cylinders arranged in V-form, a casing formed separately from the cylinders and arranged between the cylinders, said casing being supported independently'of the cylinders, horizontally arranged valves in the cylinders, and valve operating mechanism in the casing.

8. In a hydrocarbon motor, in combination, a. crank case,` cylinders arranged in V-form andsmounted on the crank case, a casing formed independently of the crank case and cylinders, and arranged between the cylinders, said casing being supported on the crank case independently of the cylinders, valves in the cylinders, and valve operating mechanism in .said casing.

vIn testimony whereof I afix my signature.
